You connect to it with your phone and it outputs audio over a 1/8" jack. I believe it runs off of 5v, so it could be integrated into this quite easily.
I'm not sure how well this sort of thing would do in a car, though. There's a lot of electrical noise in cars that might make its way into the audio. Probably worth a shot, though!
This could definitely be an option when applicable. I know that I'm going to do this update to my proto!
